bitcoin core send a -1 confirmations transaction... #6815

first , sorry my poor English and a newbie here :|

my bitcoin core server (v0.11.0 official from : https://bitcoin.org/zh_TW/download) send a transaction like this (Linux SKIP 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux)

bitcoin-cli gettransaction fbf40b5ee309576b052e482907b25d96b2c9c85b5947683b45e97d6d27395b63
{
    "amount" : -0.80392314,
    "fee" : -0.00010000,
    "confirmations" : -1,
    "txid" : "fbf40b5ee309576b052e482907b25d96b2c9c85b5947683b45e97d6d27395b63",
    "walletconflicts" : [],
    "time" : 1444581926,
    "timereceived" : 1444581926,
    "details" : [
        {
            "account" : "",
            "address" : "1A9ANWVx9GaG29abAucMXgAsXL8ePxiUsA",
            "category" : "send",
            "amount" : -0.80392314,
            "vout" : 1,
           "fee" : -0.00010000
        }
    ],
    "hex" : SKIP
}

my question is "confirmations -1" will be very often? or just I unlucky? and just skip it and re-send it?

and I get "confirmations -1" receive transaction too ...... so what can I do?

bitcoin-cli gettransaction 464103d3278f5e2cbb2afbf4280df6254a620de3b57a258d311c4f005b8a0bb1
{
    "amount" : 1.71121252,
    "confirmations" : -1,
    "txid" : "464103d3278f5e2cbb2afbf4280df6254a620de3b57a258d311c4f005b8a0bb1",
    "walletconflicts" : [],
    "time" : 1444651482,
    "timereceived" : 1444651482,
    "details" : [
    ],
    "hex" : SKIP
}

and I know maybe is this http://blog.coinkite.com/post/130318407326/ongoing-bitcoin-malleability-attack-low-s-high

so I just skip it (receive transactions) or re-send it (send transactions) is okay when the transaction be -1 confirmation? it will add txid in walletconflicts when "after" -1 confirmations ?
